No clue... no name on them, got them off Ebay. They are ceramic coated with a 3/8" flange which is nice. I'm guessing they are Chinese, as the bolts that shipped with them were 10mm heads.
I only know about the Sanderson cast headers.....as those are what were on MY 350 on vortec heads. It wasn't until I pulled them off that I saw they weren't right for it.

You want some practically new full length headers? I'll make you a great deal.

With the long tube headers open, my engine sounded like a racecar. The short tube headers open sounds like a demo derby car. Booooo...
So nice to have ground clearance again though. Lowest part on the car now is the frame.

They'll bolt up, but don't fit the vortec ports correctly. The vortec D shaped exhaust port openings are larger than the smaller square ports on the cast headers.
Even Sanderson says in red letters on their website "Does not fit Vortec cylinder heads."

Here's a pic of a set that came off some vortec heads. You can see the shape of the vortec port overlapping the cast headers smaller ports. Not enough meat on them to port them out to work either.

The true Ram Horn manifold flow pretty good.Prolly better than a set of cheap shortys.There are manifold that look like Ram Horns tho,that actually aren't.You have to be careful about what you get.IIRC,the major gains didn't show up until after 3000 RPMs.

One plus to the shorty's... I'll be able to go back to a crossover pipe again. The full length headers sent the exhaust too far to the outside of the car.

Here it is. It says it's a 64 327 but they actually bored and stroked it to 383 ci.

I watched a youtube video where they tested long tubes versus the good rams horn and there was only about a ten horsepower difference if I remember correctly. And I believe the difference was only at about 5,000 and up.

I tried to refind the article so I could post a link,but,no such luck.The article tested shortys,mid-length,& longtubes on a dyno.The shortys were the type that use stock exhaust hookups w/ 2 1/2" collector.The mid-length had a standard 3" 3 bolt header collector.I can't remember the actual gains from each offhand.Naturally the longtubes made a lot more torque & power,but,only @ higher RPMs.At lower RPMs there wasn't much difference.The type of shortys used really didn't make enuff difference to justify the costs & work to put them on @ any RPM .At higher RPMs,the mid-lengths made approx half the gains as the longtube. If I can find the article,I'll post a link.

This is the first summer I've had the headers on the car. I've scraped them a couple of times and had one major impact only going a mile or two out of a parking lot that had a bad lip at the exit. Ouch! I didn't wreck anything but it didn't sound very good.

I'm thinking of making a new set of headers this winter out of stainless with a few modifications to make them fit better with more ground clearance. It shouldn't be too hard if I go bythe Super Comps that are on the car and adjust them to suite my needs.

I have to drive a mile of rocky dirt road each way to leave my house. That's my biggest issue. Just crawling thru sections trying not to screw the headers up. Just not worth the headache and potential issue of catching them on something far from home.

I bought a set off ebay about 2pm...I already have them!

Who knows what I end up with eventually.... if I can't sell the full length ones for much, maybe I'll look at modifying them to fit.
